Description
Bourns®MX5A-12SA is a non-isolated DC-DC converter
offering designers a cost and space-efficient solution with
standard features such as remote on/off, precisely regulated
programmable output voltage and overcurrent and over-
temperature protection. These modules deliver up to 5 A of
output current with load efficiency of 92 % at 5 V output.
Stress in excess of absolute maximum ratings may cause permanent damage to the device. Device reliability may be affected if
exposed to absolute maximum ratings for extended time periods.
Characteristic Min. Max. Units Notes & Conditions
Continuous Input Voltage -0.3 15.0 Vdc
Operating Temperature Range -40 +85 °C See Thermal Considerations section
Storage Temperature -55 +125 °C
Absolute Maximum Ratings
Unless otherwise specified, specifications apply over all input voltage, resistive load and temperature conditions.
Caution: The power modules are not internally fused. An external input line fast-blow fuse with a maximum rating of 6 A is required.
See the Safety Considerations section of this data sheet.
